Maremma dogs bark a lot if they sense there is a predator.
At dusk and dawn you would normally here your Maremma barking if you have predators lurking around the edges of your property looking for an easy meal.
Barking, is not something you want to train out of your Livestock Guardian Dog.
Barking is the way your Maremma communicates and is normally doing so for a reason.
A Maremma uses barking as a way to deter predators and to let them know that their territory is off limits.
Puppies are vocal when they play together, and even playful adults can bark loudly.
Barking can also be a way of letting you know something is wrong such as a lamb getting caught in a wire fence.
